        Are you using our standard RRF 3.2 firmware binary, or have you built your own?

          @dc42 Use the official standard firmware. Now the problem has been solved. thank you

            If you have a few more empty PCBs, you could populate them step-by-step, beginning with the DC-DC power converter and test every function one at a time.
            Or do a shortcut test on an empty PCB, maybe some inner layers aren't OK?

            It seems, there is a lot of solder on the pads, maybe there's a heatsink/GND pad under the MPU or the MOSFETs which got too much solderpaste and caused a shortcut?

              @o_lampe I want to have a cheap DUET3. I decided to do it myself. Now it doesn't seem like a good idea

                How did you solve it?

                I asked about the firmware because the stack trace didn't seem to match up exactly with the map file for the standard firmware binary.

                  @dc42 I made a mistake 。Down to 3.0, the problem still exists.

                      Can you explain more? I would not expect the firmware to crash even if a driver failed, unless the failed driver fed injection current into the MCU sufficient to cause it to behave incorrectly. What type of driver did you connect that failed?

                        @dc42 Do you mean that the current breaks down the MUC when the drive is burned?
                        I connected a piece of TMC5160AIMG_20210204_212450.jpg

                          It's possible that a burned driver may feed current into the MCU pin driving Step, Dir, or one of the SPI signals. The input protection diodes shunt this current to Vcc (3.3V). If the current is small enough, operation of the chip will be unaffected. With somewhat higher current, the chip may malfunction, but no permanent damage will be done. Higher still and permanent damage will be done.

                          What I would ideally like to know is whether the firmware crashed because it didn't get the expected response from the driver (which I would regard as a firmware bug to be fixed), or the MCU crashed because of injection current.

                            did the parts work out to be more in the end?

                              @dc42 After hearing your explanation, I think it's ,the MCU crashed because of injection current

                                        He’s done the same with a duet WiFi variant. He’s shared images and videos on our Facebook support group for the blv cube and has stated he’s selling them, but supposedly doesn’t/can’t sell them outside of China (the veracity of that is up to the reader to decide).
